WILLIAM LEWIS GOFFNEY, OF NEVVBURG, NEWV YORK.

AUTOMATIC ELEVATOR-GATE.

SPECIFICATION forming part of Letters Patent No. 290,526, dated December 18, 1883,

Application filed April 18, 1883.

To all whom it may concern.-

Be it known that 1, WILLIAM LEwIs Gonn- NEY, of Newburg, county of Orange, and State of New York, have invented certain new and useful Improvements in Automatic Elevator-Gates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates, especially, to gates employed for guarding open hatchways through which an elevator platform or car runs, and has for its object the production of a device simple and cheap to construct, ornamental in appearance, durable, and not liable to get out of order, and which will be easy and effective in operation.

To attain this end my invention consists, es-

. sentially, in a folding gate supported at one extremity upon pivots passing through a post affixed to the floor near the hatchway. Secured to the upper rail of the gate, near the pivot, is an arm, upon which an adjustable ball or weight is mounted in such a manner as to act as a counter-balance, rendering the resistance of the gate to the elevator in passing merely nominal, thus requiring but little expenditure of power to open the gate, the closing being effected by the weight of the gate itself. Attached to the gate, near the upper pivot, are curved arms, adapted and arranged to engage with projections upon a standard at the corner of the elevator-platform. When a car is employed, the projecting catches may be secured thereto, said catches being so arranged as to be thrown back out of the way when it is desired that the elevator shall pass up or down the shaft and the gates remain closed.

In the drawings, Figure 1 is a view in elevation of my improved automatic elevatorgate closed, and Fig. 2 is alike view of the gate open. Fig. 3 is a side elevation of aportion of the platform, ,showing the standard affixed thereto. Fig. 4 is a reverse elevation of said standard.

Like letters of reference, wherever they occur, indicate corresponding parts in all the figures.

A is the floor of a building wherein my gate is employed.

(No model.)

B are guides for the elevator-platform, constructed in the usual manner.

The gate is formed of an upper rail, 0, and lower rail, 0, connected together by upright slats D, which are movably secured to said rails by bolts or rivets c. Said gate may be made of iron or wood, as is considered preferable.

E is a curved post, affixed to the floor at the side of the elevator shaft or hatohway. F is an arm attached thereto. A curved hinge, extends from rail 0 to post E. Rail 0 passes between arm F and post E, playing upon a pivot, f, secured in the rail. Rail O is prolonged by an arm, G, bearing an adjustable counterbalancing-weight, G, held in proper position by a set-screw, H, said weight regulating the descent of the gate after the elevator has passed. Pivot f extends through post E, and bears upon its inner extremity a curved two-part arm, I, the upper end whereof is affixed in a movable manner to an arm, J, fulcrumed at j to post E. The lower extremity of arm I terminates in a curved portion, 1'.

K is the elevator-rope, attached to the yoke L of platform M.

N is a standard affixed to one corner of said platform. Upon the upper end of this stand ard is mounted a thimble, I, made vertically adjustable by means of bolt p. R and R are catches or fingers, affixed to said thimble in such a manner that they may be thrown back out of the way, as indicated by the dotted lines in Figs. 3 and 4, when it is desired to have the elevator pass up or down and the gate remain closed. 7

T is a spring adapted and arranged to hold finger R in a proper position for opening the gate upon the downward movement of the car, but allowing it to pass arm J upon the upward movement.

W is a forked standard, into which the free end of rail 0 falls, holding the gate against displacement.

When constructed and arranged in accordance with the foregoing description, the operation of my gate is as follows: As the car passes upward, finger R comes in contact with arm 6, carrying the gate with it to the position shown in Fig. 2, holding it there so long as the elevator-platform remains upon a level with the floor; but as it ascends the finger becomes disengaged, the gate gradually closing of its own weight. Upon the descent of the car, finger R bears upon arm J, raising the gate, as before, and allowing it to gradually close after the car has passed.

Having now fully described my invention what I claim as new therein, and desire to secure by Letters Patent, is

1. An automatic elevator-gate hinged at one extremity to a post affixed to the floor at the side of the shaft or hatchway, and having an adjustable counterbalancing-wcight, substantially as set forth.

2. In an automatic elevatorgate of the character herein specified, rails G and 0, crosspieces D, curved hinge 0*, arm G, and counterbalancingweight G, the whole combined substantially as set forth. 2o

3. Rails 0 and O, cross-pieces D, curved hinge C arm G, and adjustable weight G, in combination with curved arms affixed to said gate and post E, substantially as set forth.

4. RailsO and O, cross-pieces D, hinge C, 25 arms G, I, J, and z, weight G, post E, standard N, fingers R and R, and platform M, the whole combined and arranged to operate substantially as shown and described.

In testimony that I claim the foregoing I 30 have hereunto set my hand in the presence of two witnesses.
